More Oxygen Hype:
"Magnesium-Based Oxygen Therapy"

Stephen Barrett, M.D.

"OxCgen Advanced Activated Oxygen for Colonic Cleansing & Health" is
said to contain 500 mg of magnesium oxide, 75 mg of vitamin C, 25 mg of bioflavonoids
packaged in a vegetable-based capsule. It claimed to "release activated
oxygen—a
unique and powerful mixture of oxygen and ozone - initially into the digestive
tract." According to a site that promotes it:

This powerful cleansing
'activated oxygen' can give the entire tract the kind of clean it
has been wanting for years.

After cleansing and releasing, the impacted
matter and dead fungal components are then gently released by
the magnesium in the capsules.
After oxygenating the colon, the gases released by the reaction
of these capsules with the digestive acids are then absorbed and
distributed throughout the body.

It is widely believed that a clean colon is pivotal for optimal
health. These capsules have proven themselves to have the ability
to clean out impacted matter from the colon and thus revitalize
the entire digestive and assimilation process.

Besides regular and easy bowel movements OxCgen can also help
reduce weight.
Digestion is basically a process of burning food and insufficient
oxygen in the colon leads to incomplete burning/digesting of food
which is then often stored as fat for later digestion. You thus
still feel hungry and eat some more. Which again ends up being
stored as fat and the cycle continues. It is not uncommon for
substantial weight loss to occur within a few weeks of initiating
a program of OxCgen cleansing.

As well as having a regular clean
bowel and weight loss OxCgen, as oxygen is used by the brain you
will also be thinking more clearly as well.

Other so-called "magnesium-based oxygen therapy products" are
marketed with similar claims. Colosan, Homozon (sometimes spelled
Homozone), and Oxy-Powder contain no vitamin C. They are claimed
to work by "oxidizing
toxins and fecal matter in the bowel and not by irritating it as
with conventional laxatives."

I do not believe these claims are valid. They are based on
outmoded concepts that intestinal contents stick to the the intestinal
walls, interfere with passage of the stool, and need to be cleaned
off to make people healthy.
No such process occurs [1,2]. Doctors who examine the intestinal
tract with medical instruments see no evidence of such a
process. Moreover:

Magnesium oxide, being a laxative, can soften the stool,
but this provides no general health benefit and could cause nausea
and cramping.

People who eat adequate
amounts of fruits and vegetables will get all the vitamin C and
bioflavonoids they need and do not need supplements.

The oxygen-related claims are pure hype. The digestive
process is not enhanced by having extra oxygen available.

Bowel movement regularity
has no significant effect on body weight. The most that a laxative
can do is cause diarrhea that results in extra water leaving the
body, causing dehydration. This provides no health or long-term
weight benefit and can cause health problems if done too much.
The weight will return when the water is restored by eating or
drinking.
